DETAILED DESCRIPTION

Applicant recognized that currently available configurations of wearableelectronics lacked sufficient ergonomic compatibility with the humanbody to have the wearable electronics feel as though they were anintegral portion of a wearer's body, or would not affect the ability ofa wearer to perform a variety of daily activities, including exercising.Furthermore, Applicant recognized that it would be desirable to provideelectronic devices and electronic functions which are hands-free and canbe worn on the surface of the body in a biologically fit manner. Theembodiments of the present disclosure provide a convergence betweenelectronic products, and biological, anatomical, and biomechanicalaspects of the human body while providing hands-free and interchangeablewearable electronic apparatuses that can interact with human senses andphysiology of a human body in a practical manner.

In addition, conventional “hand-held” devices require that they be held.While some cellular phones and digital players have accessories thatpermit the user to operate the device without having to hold it byhaving a second device, using such apparatus and accessories iscumbersome, and it is necessary to carry and store the accessories untilthey are actually used.

Moreover, hand-held devices are easily lost or misplaced, and unattendedhand-held devices can be easily stolen. It would be very useful to havea non-hand-held and hands-free device that can be worn in a comfortable,non-obtrusive, and biologically-fit manner without requiring the user tocarry extra devices in addition to equipment already being worn on thebody. Embodiments of the present disclosure allow hand-held devices tobecome hands-free devices and to be worn on the body.

The risk of exposure to radiation may be a serious problem with wearableelectronics. For example, cell phones and other computing andcommunication devices all emit radio frequency (RF) energy. RF energy isa form of electromagnetic radiation that can pose cancer risk to theuser. Cellular phones' main source of RF energy is produced through theantenna, and most phones are held close to the side of the head when thein use. The closer the antenna is to the head, the greater a person'sexpected exposure to RF energy.

RF energy produced by cell phones may affect the brain and other tissuesin the head because hand-held cell phones are usually held close to thehead. Researchers have focused on whether RF energy can cause malignantbrain tumors. The salivary glands also may be exposed to RF energy fromcell phones held close to the head, and cancer of salivary glands hasbeen associated with cell phone use.

An alternative to hand-held devices are Bluetooth® headsets. However,Bluetooth® headsets also emit RF energy. While many earpiece devicesemit lower levels of radiation than cell phones, the earpiece does putthe source of power closer to the brain. Therefore, Bluetooth® headsetscan cause the same problems as hand-held cellular phones. Besides, thecell phone itself continues to emit radiation locally and then throughthe body to reach the Bluetooth headset in the head, increasing exposureto radiation.

It is an object of the present disclosure to provide a wearable holderthat houses an electronic device and avoid or minimize exposure toradiation.

The present disclosure teaches a convergence between electronic productsand the anatomical, and biomechanical aspects of the human body whileproviding a series of hands free wearable electronic apparatuses thatcan interact with human senses.

The present disclosure provides a fully compact system when not in use,and which allows full interaction of the device with vision, hearing,speech, and tactile function while being used.

It is yet another object of the present disclosure to provide hands-freesupport structure for housing electronics.

These and other objects of the present disclosure, as well as many ofthe intended advantages thereof, will become more readily apparent whenreference is made to the following description taken in conjunction withthe accompanying drawings.

In describing an exemplary embodiment of the present disclosureillustrated in the drawings, specific terminology will be used for thesake of clarity.

The overall length of headphones 660 inan exemplary embodiment is equal to or less than 60 cm, and in anotherpreferred exemplary embodiment, is equal to or less than 40 cm, and inyet another most preferred exemplary embodiment, and is equal to or lessthan 20 cm. The preferred length of wire of headphones 660 ranges from20 cm to 60 cm. Attached at a first end of headphones 660 are a left earbud 666 and a right ear bud 668 for listening. Attached at a second,opposite end of headphones 660 is a connector 658, which is configuredto mate with another connector on an associated electronic device. Thelength of the headphones 660 is designed to eliminate excess length foruse with a cellular phone being housed in the holder, which makes theheadphones unobtrusive, convenient, and safer for the user, since theshorter length reduces the chance for headphones 660 to be caught onobjects during movement of the user. Headphones 660 are specificallydesigned for configurations where an associated electronic device ispositioned equidistant, or approximately equidistant, from both ears ofthe user, such as the configuration shown in FIG. 10. The configurationof headphones 660 allows the user to be tangle free and helps to reduceexposure to radiation from an associated electronic device, as shown inFIGS. 7, 10, and 13, by the electronic device, such as a cell phone,being positioned away from the ear canal, an opening to the brain andthe area of highest risk for radiating the brain and developing cancer.

FIG. 20 shows a perspective view of specialized headphones 852 used withthe holder. With these headphones 850, one side (wire) 854 is longerthan the other side (wire) 856. The length of shorter side (shorterwire) 856 in an exemplary embodiment is ≦45 cm, and is preferably ≦30 cmand is most preferably ≦20 cm. The length of the longer side (longerwire) 854 in an exemplary embodiment is in the range of 15 cm to 30 cmlonger than shorter side (short wire) 856. Headphones 852 have adifferent length on each side because users usually wear a holder 858 oneither side of their body and not in the middle, as shown in FIGS. 13,17, 21, and 22. It is understood that even when user wears holder in themiddle of the body, overlaying the heart region and end of the sternum,such as shown in FIG. 10, wires of dissimilar lengths can be used, inwhich one side a shorter wire is disposed in one ear and the second wire(longer wire) is disposed behind the neck to reach the opposite ear.

While the lengths of longer and shorter sides 854 and 856 are mostoptimized with a ratio of lengths in a specific range of lengths. Theratio of longer to shorter lengths in an exemplary embodiment is 5:2when the length of longer side 854 is approximately 50 cm and the lengthof shorter side 856 is approximately 20 cm. However, the ratio can rangefrom about 1.25:1 to about 3:1, depending on the length of each side. Itshould be noted that as the lengths of the wires increases, the ratiodecreases. The lengths of the earphones are designed to eliminate excesslength when used with the holder of the present invention housing acellular phone with ear phone, which makes the earphones less obtrusive,convenient, and safer for the user. Additionally, headphones 852 reducethe chance of tangles as the user moves and helps avoid radiation froman associated electronic device, such as holder 858.

FIG. 20 shows a perspective view of specialized headphones 852 used withthe holder. Headphones 852 have a different length on each side becauseusers usually wear a holder 858 on either side of their body and not inthe middle, as shown in FIGS. 13, 17, 21, and 22. The lengths of theearphones are designed to eliminate excess length when used with acellular phone, which makes the earphones less obtrusive, convenient,and safer for the user. Additionally, headphones 852 reduce the chanceof tangles as the user moves and helps avoid radiation from anassociated electronic device, such as holder 858.

When the holder is used in the middle of the body, at the level of theheart and lower part of the sternum, as shown in FIG. 10, and when onewire is disposed behind the neck, as described elsewhere herein, wiresof particular dissimilar lengths are used. Exemplary preferreddimensions in this embodiment are 33 cm for the shorter wire and 65 cmfor the longer wire, with a range of plus or minus 15 cm for both thelonger wire and the shorter wire.

FIGS. 23-25 show a holder in accordance with an exemplary embodiment ofthe present disclosure and indicated generally at 900. Holder 900includes a plurality of arms 902 on a back side 904 and a front side 906that extend outwardly and which allow holder 900 to be positioned in avertical or standing orientation; i.e., arms 902, when opened as shownin FIG. 24, permit holder 900 to extend perpendicular to a horizontalaxis such that back 904 and front 906 face in directions that areapproximately parallel to a horizontal plane 908, such as that shown inFIG. 26. Arms 902 allow user 910 to watch holder 900 hands-free, asshown in FIG. 26. Additionally, arms 902 are sized and dimensioned toprovide sufficient distance to decrease the exposure of user 910 toradiation substantially if user 910 is talking on holder 900 when holder900 houses a cellular phone. Cellular phones generate RF energy throughan antenna that is generally internal to the cell phone, and most suchphones are held close to the side of the user's head when in use. Thecloser holder 900, and the antenna of a cell phone is to the head ofuser 910, the greater the exposure of user 910 to RF energy. The amountof RF energy absorbed by user 910 decreases significantly withincreasing distance between holder 900 and user 910. The length of arms902 in an exemplary embodiment is in the range of 30 mm to 35 mm. Inanother exemplary embodiment, the length of arms 902 is in the range of25 mm to 35 mm. In yet another exemplary embodiment, the length of arms902 is in the range of 10 mm to 25 mm. Each of these lengths isconfigured to decrease the exposure of user 910 to potentially harmfulRF radiation.

In the exemplary embodiment of FIGS. 23 and 24, each arm 902 pivots on ahinge that is internal to holder 900, which is not visible. Each arm 902is provided with two locked positions. The first locked position isshown in FIG. 23, where each arm 902 is stored or stowed to avoidprotrusion of arm 902 from a housing 912 of holder 900. The secondlocked position is shown in FIG. 24, where each arm 902 can be lockedinto the open position shown in FIG. 24. By being locked into theposition shown in FIG. 24, arms 902 improve the stability of holder 900when in the upright, vertical, or standing position shown in FIGS. 24and 26. The locked positions may be established by a frictionalengagement of each arm 902 with a feature of holder 900, such as anover-center mechanism, a releasable lock, or other feature thatmaintains the positions of each arm 902 as shown in FIGS. 24 and 26.

FIG. 27 shows a back view of a holder in accordance with an exemplaryembodiment of the present disclosure and generally indicated at 920.Holder 920 includes a plurality of anchors 922, and, in the exemplaryembodiment of FIG. 27, one anchor 922 is positioned on each of thecorners of holder 920. Anchors 922 can be attached to another device,mechanism, or apparatus, such as one or more flexible arms 924 shown inFIG. 28. Flexible arms 924 are configured to retain a position, once arm924 is positioned by a user. Such positions may form a shape. An arm end926 of each flexible arm 924 may be configured to include an attachablefeature, such as hooks 928. By providing anchor 922 in each of the fourcorners of holder 920, a user is able to attach a device, mechanism, orapparatus, such as flexible arms 924, in a plurality of orientations,such as those shown in FIGS. 29-32.

FIG. 29 shows a user 930 who has anchored holder 920 on a back portionof a chair's headrest 932 with flexible elongated arms 924 positioned tograsp sides of headrest 932. Flexible elongated arms 924 are able toclamp the sides of headrest 932 because arms 924 are able to retain adesired shape and position. Alternatively, flexible elongated arms 902can wrap around headrest 932 or hook above headrest 932, as shown inFIG. 32. This embodiment allows the user to sit comfortably in a seatwith the display of cell phone in holder being aligned with the eyes ofthe user, instead of the user looking down and straining the neck whileholding the cell phone with hands. FIG. 33 shows an exemplary anchoringsystem comprised of a C-clamp 934 connected to a holder 940 and anchoredto a chair headrest 932, said C-clamp having right and left pads 936,938 for applying pressure and to position the C-clamp in place.

Headrest 932 is chosen as an illustration and not a limitation to thescope of the present disclosure. Flexible elongated arms 924 can graspor hang from many structures because of the flexibility of arms 924 andthe ability of arms 924 to retain the desired shape and position.Elongated arms can include a series of configurations and materials, andby way of example, telescopic arms, gooseneck arms, C-clamp arms, andthe like and may include a variety of pressure mechanisms and springsfor anchoring holder to an article of manufacturing such as chair headrest.
